Although Feng Nuo was not satisfied with the fact that the machinery factory only hired one new worker who had just graduated from a vocational school and entered the factory, it was better than nothing. To actually trial-produce the relay, the trivial work was much more trivial than the "design" that had been discussed before.
There are many, and these things don't require skilled technicians. Having a helper can free up a lot of his energy. He was thinking about the schedule in his mind, and he didn't realize that the young man in front of him occasionally glanced in the direction of his office.
Feng Nuo spent the past two days studying the enameled wire manufacturing information given by Faraday without food or sleep. Generally speaking, Faraday also tried to produce enameled wire, and the route was quite complicated. There were modified tung oil and modified raw lacquer, but they didn't work.
Either way, the wear resistance of the paint film is very poor and must be reinforced with cotton yarn. It can barely be used on motors - the disadvantage is that it naturally affects the service life.
"It seems like it's not too difficult." Feng Nuo read the information and felt that he was still confident that he could do it.
The Electric Power Port also generously gave him a portion of silicon steel sheets that were said to be of good quality. This was a step into the relay manufacturing pit. I heard that he was interested in this career, and the Power Port and the veteran who were interested in electronics
They all sent letters and phone calls to offer advice. For a time, Feng Nuo's residence and office were filled with people, and his motivation increased a little.
Once he got involved in the project, he learned that there were people in Laigao doing things like enameled wire, but that was in another research direction. The name of the project was "Electronic Components Development Group", and the host was his colleague Xiu Yuxuan.
Xiu Yuxuan originally had a background in communications engineering. Since landing, his main job has been to maintain the computer room of Lingao Telecom. Although the work location is different, the work is basically the same.
Seeing that there was really no future in the computer room maintenance job, Xiu Yuxuan took Zhong Lizhi's route and entered the "Institute of Electronics" under the Ministry of Science and Technology, serving as the director - of course, the polished commander.
Xiu Yuxuan is busy "restoring" various electronic components at the Institute of Electronics. Speaking of which, manufacturing electronic components is not difficult. The difficulty is that the raw materials rely heavily on fine chemicals, so Director Xiu's work is not smooth.
Now I heard that someone wanted to gnaw on the bones of relays. Director Xiu not only paid a visit in person, but also exchanged experiences on running projects and maintaining computer rooms. Finally, he gave me a set of technical information that he specially collected from the big library.
After sending Xiu Yuxuan away, he casually opened the folder Xiu Yuxuan sent. The first one was a mimeographed booklet "Simple Manufacturing Method of Enameled Wire". There was also a line below: Internal readings of the Ministry of Science and Technology, please save them.
Looking at the title of the booklet, Feng Nuo felt a murmur in his heart. When he opened the preface, although many contemporary words were removed, the familiar writing style still made Feng Nuo immediately understand that this was a book written during the Great Leap Forward period.
Compiled and distributed the so-called "Made by Local Methods" pamphlet.
Feng Nuo's eyelids jumped again. In the past two years, the Manufacturing Directorate and the Planning Institute have issued multiple documents to various departments, specifically requesting the industrial, scientific and technological, and military technology research and development groups to use caution in the use of the Great Leap Forward and even the "pre-liberation"
"Original method, simple method". Pay attention to standardization issues and eliminate outdated technologies. In particular, it is pointed out that the use of such indigenous methods must be done in small batches first, and cannot be blindly put into large-scale production.
But for him, a 100% layman, this type of booklet is easier to understand and experiment with.
"Forget it, we will keep it simple because it is crude. None of our Lingao things started from the imitation of local methods. Why should our project be in line with the old time and space standards from the beginning?" Feng Nuo thought to himself.
"The entire production process of enameled wire includes drawing, painting, baking and winding. Special enameled wire coating is applied to clean bare copper wire. After baking at a high temperature of 300-400 degrees Celsius, the coating is tightly aggregated.
The ground is wrapped on the line and then cooled to become an enameled wire. This is a continuous production process. During the production process of a whole enameled wire, each part goes through each process one by one without stopping."
This book seems to be quite reliable, and it is written quite clearly. It also honestly tells who was consulted and which factories were consulted for their craftsmanship. A table in the book also records the number of paint layers under each wire diameter, and the number of paint layers.
The thickness and room temperature resistivity are all extracted from industrial data of the former Soviet Union.
According to the records of this simple method, the equipment for boiling insulating paint is extremely simple: basically a stove and a pot. Of course, this pot is specially made. The pot lid is equipped with a flue, and is also equipped with a thermometer, stirring rod and Grignard tube.
, the stirring rod can be extended through a small door on the pot lid. The Grignard tube is used to measure the viscosity of the paint. The thinner the wire diameter, the lower the viscosity of the paint should be.
He looked at the equipment and tools listed in the brochure, and there seemed to be nothing that Lingao couldn't make.
The formula of the insulating paint is 17% phenolic resin, 43% tung oil, 0.35% lead oxide, 0.1% cobalt desiccant, and 40% lamp kerosene. Seeing this, Feng Nuo breathed a sigh of relief. All these raw materials can be produced by Lingao.
He didn’t know if there was phenolic resin, but in the middle school chemistry class, synthesizing phenolic resin was the simplest organic experiment. As for the raw materials phenol and formaldehyde, Lingao’s chemical plants are manufacturing them; needless to say, tung oil is considered a Chinese tradition.
It is a bulk export trade commodity and is widely used by the people. Even in the industrial system of the Senate, it also plays an important role. Lead oxide has been available since ancient times, which is the so-called Tantric monk. This is a by-product of alchemy and is a sulfide.
The galena-like mineral galena is a product of the furnace bottom deposited when refining silver and lead. It is a very important Chinese medicinal material. Ancient cosmetics also used this as a whitening agent. It is not difficult to prepare directly; of course kerosene has
Yes; only cobalt desiccant is left. The preparation method is also introduced in the information, and it is mentioned that manganese desiccant made of manganese dioxide can also be substituted. The Senate controls manganese ore, so it is not a problem...
Feng Nuo felt more and more that this information was good. There was also a basic design of the enameling machine. Some of the substitutes were indigenous methods, such as replacing the steel of the frame with bricks/wood, replacing the painting wheel with multi-groove porcelain insulators, and making the oven with scrap materials.
Etc., there is no need to do the same thing in Lingao. All-steel equipment and necessary ceramic components can be produced by ourselves.
More importantly, the empirical data in the data are relatively complete, such as the boiling temperature range, the drying temperature range, the distance between the wire and the furnace wall, the amount of desiccant, the line speed of the painting process, and the felt used for polishing.
The thicknesses are all empirically determined. Even the preparation of acids and alkalis used in ventilation equipment, copper wire drawing and cleaning equipment are also introduced. However, Von Nuo does not need to consider these. At least for wire rods, he plans to rely entirely on the standard parts factory and the factory.
The basic facilities are also ready, and acid and alkali can be directly withdrawn from the planning institute warehouse.
Finally, Feng Nuo wrote down the finished product specifications and quality inspection methods recorded in the materials. Since it was to be done, the specifications and quality that could be achieved by the local methods of the Great Leap Forward period were the minimum requirements.
In the next few days, Qian Yuzhi was ordered by Feng Nuo to move around. Not only did he carry various raw materials here and there, he also had to test the insulating paint according to the formula without any protective measures every day.
Although the lacquer boiling pot has been ordered, it is a special product and requires a certain manufacturing period. So what Feng Nuo gave him was really an ordinary iron pot. Even the Great Leap Forward brochure said the pot lid was equipped with a flue and a stirrer.
It's not as good as a pot in your mouth.
The cooking temperature is as high as more than 200 degrees, and the drying temperature is 300 to 400 degrees. The smell is even more touching. Naturally, there are no gas masks, not to mention 3M masks. The labor protection that Qian Yuzhi can get is just one.
Lingao's self-produced 24-layer gauze mask plus a pair of bulky labor protection glasses.
In order to prevent him from being burned, he wore thick work clothes while the paint was boiling. Within a few hours, the clothes looked like they had been fished out of the water.
Because the pot is heated directly, temperature control is very difficult. Overheating often occurs. Once the raw materials are scrapped, not only will the hard work for several hours be in vain, but the commander's face will also become very ugly.
Qian Yuzhi was so hot that he sweated profusely every day and became dizzy from the smoke. When he got home, he would collapse on the bed like a dead dog, completely forgetting that there was a beautiful girl wearing a liberal arts college uniform living in the attic.
Listening to Qian Yuzhi's snoring downstairs, Li Janai couldn't sleep at all. It wasn't because he snored - she had something on her mind.
In the darkness, she stared at the beams under the roof with her eyes wide open - she had cut off contact with the "organization" for several months.
This was something that had never happened to her since she entered the Lingao quarantine camp three years ago. It seemed like a heavy stone was pressing on her heart, and it was like there was a cold gap in her heart. She couldn't help but shudder, and her body
He shrank back to the corner again and wrapped the blanket tightly around him.
When she was in the quarantine camp, she was an orphan and was born thin, so she was promoted to a "monitor" in the quarantine camp and went through several more periods of quarantine. It was not until a year later that her body growth accelerated. Due to her good performance in the monitoring work, her figure
Her appearance and appearance were also good. Then she was assigned to a maid school and was officially developed into a "hidden worker" of the General Administration of Political Security. In the past two years, she received a lot of secret training. After the maid school and the restructuring
The College of Arts and Sciences continues to work in internal security.
When she graduated, the "organization" informed her that a new "superior" would assign tasks to her when she was assigned to a job.
However, this was her last contact with the "organization".
As time goes by, Li Janai becomes more and more nervous. During the training, the instructor said that if you lurk for a long time or retire, you will get clear instructions. If you fail to contact the contact person after the deadline, you will be treated as a traitor. But after working in Tiandihui for a few months
Since then, no one has contacted her. According to discipline, she cannot take the initiative to contact her previous contacts. Now she is in a situation where she doesn’t know what went wrong. She is worried about the loneliness of being “abandoned” by the organization and the fear of being “dealt with by the organization”.
"The panic gradually eroded her spirit.
